Cleaning the External Surfaces of the Server
Caution
■
To avoid altering the material and color of the server, do not
use volatile solvents such as thinner and benzene to clean
the server.
■
The power receptacle, the cables, the connectors on the
rear panel of server, and the inside of the server must be
kept dry. Do not moisten them with water.
For daily cleaning, wipe the external surfaces of the server with a dry soft cloth
If stains remain on the surfaces:
1. Make sure that the server is off-powered (the POWER/SLEEP lamp goes off).
2. Unplug the power cord of the server from a power outlet.
3. Wipe off dust from the power cord plug with a dry cloth.
4. Soak a soft cloth in neutral detergent that is diluted with cold or lukewarm
water, and squeeze it firmly.
5. Rub off stains on the server with the cloth prepared in Step 4.
6. Soak a soft cloth in water, squeeze it firmly, wipe the server with it once again.
7. Wipe the server with a dry cloth.
8. Wipe off dust from the fan exhaust opening on the rear of the server with a dry
cloth.
Cleaning the Interior of the Server
One important item in a good maintenance program is regular and thorough cleaning of
the interior of the server, especially around the motherboard.
Dust buildup inside the server can lead to several problems. As dust acts as a thermal
insulator, a buildup can prevent proper system cooling. Excessive heat will shorten the
life of server components. Also, dust may contain conductive or corrosive materials
that can cause short circuits or corrosion of electrical contacts.
How often you should clean the interior of the server depends on the environment in
which it is located. For most office environments, you probably should clean the server
every 12 months. For more severe environments, clean the interior every 6 months.
